What are the "text deleted" AC1 etc, should we not use the data inside them? 4

[Pretty Girl7]

Probably the worst question in this forum.

In Eurocode documents, I often see the following symbols "AC1, AC2" etc

I know it means "deleted text" etc
But It confuses me as I have seen these symbols in the text as well as around the tables as well.
Are they asking us not to use the table or text?

If they don't want us to use the table, where can I find the updated one?

I hope , next time you would ask real questions..

@HTURKAK, Thank you, so, we don't have to look for any other document for amendments, it's already been amended, so we can just use the text as it is, is that correct?.

But why "EN 1991-1-7:2006 (E)" clause 1.6 (page 12) says it means deleted text?

If you had the old version open to that same place you would see text in the old version that is deleted in the new version. This is to tell you where to look for that difference in the two versions.

Text can be added. Text can be changed. Text can be deleted. These are flags marking where to look IN THE OLDER VERSION OF THE DOCUMENT to see what it USED TO LOOK LIKE.

IGNORE THE MARKINGS IF YOU DON'T HAVE THE OLD DOCUMENT.

Thanks a lot, @3DDave. Your simplified answer made it much clearer.

HTURKAK: It was a real question... I was unaware of that format, and it's the first time I've seen the word "corrigendum". I have to get out more, it would seem.

Mr. DIK, i do not normally respond if not my nick name explicitly stated..

If you have the digital copy of the mentioned standard , i am sure you would look before posting.. Moreover, if you search the digital document for AC1, AC2 etc, you would see the explanation at the first page , ( National foreword )

Just for info because I use a load of documentation which uses the same stuff none engineering related.

I don't know which documentation system it is, but its the documentation systems version tracking markers. They don't store the whole document with every change just a databases with the changes. You can turn them off and not see them which is done in some documents. But the likes of web manuals uses them to index changes so you can just forward to the next one through a 4000 page document when a new revision comes out. They are also used to generate the revision changes index at the front.

I get 2000 pages plus manuals being changed sometimes weekly and its really handy just to jump to the changes. There is also a major change flag and critical safety change flag as well. But ours have that AC1 and Ac2 flags as well.

@Alistair_Heaton
Thanks for your thoughts and information. It's interesting to know facts/matters about different non-engineering fields.

 

[Alistair_Heaton]

Well when I say none engineering related its aviation manuals which do contain a fair amount of technical documents. Just had a look and its 245 documents in my pushed library with 11 000 pages of text using web manuals.

Another one of those things that I find facinating with the Eurocodes. I heard from somebody that was involved in the development of the standards that the idea was that the standards should not vary between countries. Instead you buy for example EN 1993-1-3 (Steel) and them you can find the National Annex in a separate document. The purpose was that you should not have to buy each separate standard for the countries you work in, when most of the content the same anyway.

The some countries decided that working two documents was "difficult" and included the NA in the standard. So in some cases we have to buy the complete standard to get the NA.

The same happened with the AC's, corrigendums. When a standard is revised it should be sent for notification the the other member states. So the AC's were publised separately and that appearently bacame to diffcult . The UK may be a bad example since they left the EU but this approach probably improves the sales for British Standard .

 

[Alistair_Heaton]

I am told that the engineering standards side of things in the EU was basically British plan and built and most of it is actually BS standard.

Its also now rapidly going to poo as the French are mainly in charge of documentation. Which apparently the only thing that could make it worse is if the Greeks were doing it.

And the bulk of the people who built and ran it were British and are now not involved and gone back to the UK to do BS. Similar situation with the medical certification stuff.

And before people get upset it was a Polish Engineer that I was talking to.

I worked with projects in different parts on Europe before the Eurocodes. My experience is not that the Eurocodes are based mostly on British Standards. There are british influences but I know of specific models that are from experts in Italy, Denmark, Sweden and so on.

I once heard a joke steel professor (not a german) that the reason for the numerous standards regarding steel are the number of steel professors in Germany.

And I heard from a collegue involved in the development that the british should not leave the project. But that statement was from before they actually left the EU.

There is probably different versions regarding who did what and where they are now. We'll see when the next generation of Eurocodes arrive.
